Afather is 1 year older than 3 times the age of his son. the son is 20 years old.

let f = the age of the father.

which formula would calculate the father's age?
1. f=3(20-1)
2. f + 1 = 3(20)
3. f - 1 = 3(20)

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
